Flow Control
GF125C-202440
Brooks GF100/GF120/GF125 Series Mass Flow Controller
About this part
GF125C-202440 is a configured Brooks Instrument GF-series metal-sealed thermal mass flow controller identifier observed in Sonisys auction records. Official Brooks GF100/GF120/GF125 family documents support the metal-sealed high-purity MFC context, MultiFlo gas/range configurability, and family-level performance/materials data, but the exact gas, range, communication interface, fitting, valve option, surface finish, and customer configuration must be verified from the unit label or Brooks configuration record. Stored auction records observe AR 55000 SCCM context for this exact identifier
Unit-specific configuration
Historical listing records identify this part as AR at 55000 SCCM. Exact gas, range, fittings, valve configuration, and communication interface must be verified from the physical unit label.
Configurations vary. Verify the exact unit before choosing a replacement.

Key Facts
Specifications
| Part identifier | GF125C-202440 |
| Observed device type | Brooks GF-series metal-sealed thermal mass flow controller |
| Official family context | Brooks document library groups GF100, GF101, GF120, GF120XSD, GF120XSL, GF121, GF125, and GF126 under GF100 metal-sealed mass flow controllers and meters |
| Configured-unit rule | Gas, full-scale range, communication interface, valve state, fitting package, surface finish, and process options vary by configured model code and should be checked on the physical label or Brooks configuration record |
| Application domain | Official GF100/GF120/GF125 family documentation describes semiconductor, MOCVD, and other high-purity all-metal gas flow-control applications |
| Family flow accuracy | Brooks GF100/GF120/GF125 analog and DeviceNet data sheet lists +/-1% of set point above 35-100% and +/-0.35% full scale over 2-35%, based on factory N2 calibration |
| Family settling-time bins | For normally closed GF100/GF120/GF125 family configurations, listed response-time bins range from 300 ms to less than 700 ms across supported full-scale flow ranges |
| Wetted path standard | Official family data lists SEMI F20 HP compliant wetted materials, with materials and surface finish depending on configuration |
| Communication interfaces | Official GF100/GF120/GF125 family documentation covers analog/RS485, DeviceNet, and EtherCAT variants; the exact GF125C-202440 interface is configuration dependent |
| Gas/range programmability | Brooks MultiFlo documentation supports programming applicable GF-series thermal mass flow devices across supported gases and ranges |
| Stored auction gas/range context | Stored Sonisys auction records observe AR 55000 SCCM on two listings and 55000 SCCM without a parsed gas on one listing; this is auction context, not an official model-wide specification |
